TURBINE.

To all whom it may concern.-

Be it known that we, JULEs GERSAN'I, a citizen of France, residing atClapham, in the county of London, England, and GEORGES JUSTIN JOSEPHLEGRAND, a citizen of France, residing at Lancing, in the county ofSussex, England, have invented new and useful Improvements in Turbines,of which the following is a specification.

This invention relates to improvements in rotary motors or turbines.According to same, steam or other fluid is caused to pass into a curvedor elbow-shaped slot or opening in a fixed diaphragm or part in acylinder, thence into an obliquely arranged curved or elbowed slot in apart secured on a rotatable shaft, thence into a further slot in asimilar fixed diaphragm or part similar in shape to the first one,thence out of the cylinder at the far end, through an obliquely arrangedpassage'or pipe and into the cylinder at the first end again whence itpasses into the next slot or opening in the first fixed part through thesecond slot or opening in the rotatable part, through the next slot oropening in the second fixed part and so on to a further oblique passageor pipe to the first end again, the operation being repeated until thewhole circle of the cylinder and the series of openings in each part hasbeen traversed and the exhaust reached.

In the drawings which illustrate one means for carrying the inventioninto effect Figure 1, is a longitudinal elevation partly in section online ww Fig. Fig. 2. is a sectional elevation on line o v Fig. 1. Fig.isa sectional elevation on line y-y Fig. 1. Fig. 4. is a diagrammaticview showing the direction taken by the motive fluid, and, Fig. 5. is asection on line Fig. 2. showing the construction of the opening of theinlet or exhaust opening and of the wall passages to the fixeddiaphragm.

The motor may consist of two concentric cylinders, the space betweenbeing divided into a number of separate compartments preferably arrangedobliquely around the walls or as shown in the drawings the cylinder a isprovided with a series of oblique passages running the whole length ofthe cylinder on the outside. Each of these passages, with the exceptionof the two uppermost, to which the inlet and exhaust pipes c and (Z areformed in their outer half with one opening to two openings h in theinner half, the divisions may, however, be varied as desired. Theopenings 9 are adapted to register with the ports i in the wall of thecylinder, while the intermediate diaphragms f, secured to the cylindera, which may be employed to any number have straight through openings itonly. A further series of diaphragms, drums or parts arrangedalternately with the fixed diaphragmsf are secured to the central shaft7; to be driven so as to permit of their free rotation, within thecylinder (1. These latter diaphragms are provided with a series ofsimilarly curved but obliquely arranged openings Z adapted to registerwith the straight through openings in the fixed diaphragms arranged oneither side thereof.

The operation of the motor is as follows: Assuming that the motive fluidis entering the cylinder through the pipe 0, it will then pass into thedivision indicated on Fig. 2. by g in communication therewith thencethrough the passage or passages W to the obliquely arranged passages Zin the adjacent rotating diaphragm thence through the correspondingstraight through passages in the next diaphragm and. so on as indicatedby the arrows in Figs. 2. and 4, until the division 9 at the other endis reached, which division opens into the port 4, at the end of thepassage b through said. passage into the division 9 and so on until theport i in the passage b is reached, to which passage the exhaust pipe (Zis connected.

Although the passages in the fixed and movable diaphragms, drums orparts are shown substantially radially curved, they may be of any otherconvenient shape, such as elbowed, so as to obtain the maximum operatingsurface and also so that the passages in the movable diaphragms inpassing those in the fixed ones may do so with their edges more or lessparallel to each other which would not be the case with straight radialpassages. It is also obvious that the passages may be formed by means ofvanes on the exterior of the rotating part and the inte rior of thecylinder respectively.

If it is desired to reverse the direction of I rotation of the shaft 7cit is only necessary to make the exhaust the inlet and vice versa. Anysuitable valve gear may be provided for effecting this result and forotherwise controlling the supply of motive fluid, that shown in thedrawings being given by way of illustration.
